Matthieu NOBLET released a plugin Recall_last_tool.rb that worked with SU7, but I've found it didn't appear to work with SU201* versions.
Depending on what kind of errors occur, that could be because SketchUp changed from Ruby 1.8 to Ruby 2.0 in 2014, or it could be due to changes in the SketchUp API. It is quite common for older plugins, especially way back to SU7, to need updating for new versions of SketchUp.
